%X Nine compounds were isolated from the ethanolic extract from the whole plant of Elephantopus tomentosus Linn. On the basis of spectral data, their structures were identified as epifriedelanol (1), lupeol (2), 6-deoxyisojacreubin (3), butulinic acid (4), ursolic acid (5), ferulic acid (6), 3-formylindole (7), pinellic acid (8) and 30-oxo-lupeol (9), respectively. All compounds were obtained from Elephantopus tomentosus for the first time. Compounds 6 and 7 had inhibitory effect on Staphylococcus aureus, as well as compounds 6 and 8 exhibited inhibitory effects on Ralstonia solanacearum by paper disk diffusion method.
